CHURN-POWER.

SPECIFICATION forming part of Letters Patent'No. 533,641, dated February5, 1895.

Application filed September 13, 1893. $erial No. 486,420. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. GOODWIN, a citizen of the United States,residing at- Lowell, in the county of Benton and State of Arkansas,haveinvemted a new and useful Churn-Motor, of which the following is aspecification.

The invention relates to improvements in churn motors.

The object of the present invention is to improve the construction ofchurn powers and to provide a simple and inexpensive one by which buttermay be rapidly produced.

The invention consists in the construction and novel combination andarrangement of parts, hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure l is a perspective view of a churn motorconstructed in accordance with this invention. Fig. 2 is a transversesectional view. Fig. 3 is a detail sectional view showing the catch forholding the winding shaft against turning. Fig. at is a detailperspective view of the stock of the pendulum.

Like numerals of reference indicate corresponding parts in all thefigures of the draw lugs.

1 designates a tripod supporting frame having a triangular base formedby rods 2 and provided at its apex with a horizontal journal 3, fromwhich depends a pendulum 4. The pendulum 4c is provided at its bottomwith a holder 5, adapted for the reception of a churn body or creamreceptacle 6; and the contents of the latter are agitated byoscillations of the pendulum.

The churn body or cream receptacle 6, may be of any desiredconstruction, but is preferably in the form of a barrel and is providedwith handles to enable it to be readily lifted out of the holder orbasket 5, and it has a suitable opening and cover to enable cream to besupplied to it. The holder 5 is approximately rectangular, and iscomposed of a base 7, ends 8 and top side bars 9, having their innersides or edges reccssedand conforming to the configuration of the churnbody or receptacle.

The pendulum consists of an upper stock 10, and lower divergentsuspension bars 11, which have their lower ends secured to the holder 5.The stock is provided at its top with a bearing opening to receive thejournal 3, and it is engaged adjacent to its center by a crank shaft 12,and is provided on its inner face with a recess having a transverseportion 13, and upper and lower branches 14 and 15 arranged at oppositesides of the stock. The crank of the shaft is provided with anantifriction roller, and it alternately engages the stock at the upperand lower branches of the recess, and it operates to lift the pendulumand its weight to the end of the stroke. After the pendulum has beenlifted to the end of its stroke by the crank-shaft the crank passes intothe transverse portion 13 of the recess, and the pendulum is thenpermitted to return to a vertical position by its own weight, withoutthe aid of the crank shaft, which is held against rotation by being inthe said transverse portion of the recess; and when the pendulum hasreached and partially passed a vertical position the crank of the shaftis released, and continues its rotation to lift the pendulum to theopposite end of the oscillation, when the operation is completed, thependulum returning to a perpendicular by its own Weight. Thisarrangement insures a steadymovement of the churn power, and economizesthe power as the crank shaft is intermittently rotated.

The crank shaft carries a pinion 16, which meshes with a masterwheel17loosely mounted on a winding shaft 18 and connected with the latter by acoiled orbarrel spring 19 which hasits inner end connected with theshaft and its outer terminal connected with the master wheel. The spring19 actuates the cog or master-wheel; and the winding shaft is providedat its outer end with a crank handle 20, which is held againstretrograde rotation by a spring catch 21.

The spring catch 21 consists of a casing, which is secured to one of theinclined bars of the tripod frame, and a spring frame 22 constructed ofspring wire or other resilient material, and provided at one end whichis attached to one end of the casing, with a spring coil. The other endof the spring frame is arranged in an opening of the casing, and isprovided with a rectangular bend 23 forming a shoulder to engage thehandle of the winding shaft, and the adjacent end of the metal formingthe frame is bent at an angle to form a stop 24 to limit the outwardmovement of the shoulder. By this construction the catch presents arounded or beveled end at one terminus and a rectangular: shoulder atits other terminus, in order that in turning the handle for winding upthe spring the handle may readily pass the catch without interference,but will be prevented from retrograde rotation by the shoulder.

The pendulum has its upper end arranged within a keeper 25, and it isheld stationary when desired to stop the motor by a hook 26, which issecured to the frame and adapted to engage one of the suspension rods orbars 11. The keeper 25 extends outward from the top of the frame andreceives the stop of the pendulum, and is approximately rectangular, andis provided with depending shanks 27, which are fitted in suitablesockets of the apex of the tripod frame. It will be apparent that thechurn motor is simple and comparatively inexpensive in construction,that it is positive and reliable and capable of a rapid production ofbutter, and that the power is economically expended.

Changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

l/Vhat I claim is 1. In a churn motor, the combination of a supportingframe, a pendulum depending therefrom and comprising an upper stockprovided with a transverse recess with upper and lower branches anddepending suspension bars, a churn body, a holder or basket receivingthe churn body and conformingto the configuration of the bottom of thesame and secured to the lower ends of the suspension bars, and arotating crank engaging the stock of the pendulum and arranged in therecessthereof, substantially as described.

2. In a churn motor, the combination of a frame provided with ahorizontal journal, a pendulum suspended from the journal and providedwith a recess having a transverse portion and upper and lower branches,a keeper extending from the frame and receiving the pendulum, a crankshaft having its crank engaging the pendulum at the recess thereof,means for rotating the crank shaft, and a churn body carried by thependulum, substantially as described.

3. In a churn motor, the combiiiation of a supporting frame, a pendulumprovided with a transverse recess and having upper and lower extensionsof the same, and a rotating crank arranged in the recess of the pendulumand engaging and oscillating the latter, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedm ysignature in the presence of two witnesses.
